• Abstract:
  Much of the fundamental basis for the current lightweight concrete provisions in the AASHTO LRFD Bridge ; Design Specifications is based on research of lightweight concrete (LWC) from the 1960s. The LWC that was ; part of this research used traditional mixes of coarse aggregate, fine aggregate, portland cement, and water. ; Broad-based advancement in concrete technology over the past 50 years has given rise to significant ; advancements in concrete mechanical and durability performance. The purpose of this document is to give ; members of AASHTO Subcommittee on Bridges and Structures T-10 the opportunity to begin considering ; whether revisions to provisions related to LWC within Chapter 5 of the AASHTO LRFD Specifications are ; warranted. Five specific topics are described in this document where recent LWC research may be sufficient to ; warrant consideration of a revision to the AASHTO LRFD Specifications. For each topic, the current articles in ; AASHTO LRFD are described, some of the recent research efforts are mentioned, and then potential revisions ; are outlined. This document served as supplemental information in support of the discussion that occurred at the ; March 2012 T-10 meeting in Chicago, Illinois.
